Aim and objective: The purpose of this study was to compare the pulp testing methods (pulse oximetry and electric pulp test) in primary and young permanent teeth of children.Materials and methods: The study included a total of 155 children aged 4 to 15 years. Twenty children formed control group I. Study group included all healthy, 85 primary 2nd molars in group II and 85 permanent 1st molars in group III. Fifty children needing endodontics treatment formed test group IV. The readings were recorded as true positive (TP), false positive (FP), true negative (TN), false negative (FN). Based on this, the sensitivity, specificity, positive predictive value and negative predictive value were calculated for each method. The results were statistically analyzed using Chi-square test.Results: On comparing pulse oximetry with electric pulp test ‘p-value’ was found to be 0.487 and 1.00 for groups 1 and 2 respectively and was statistically not significant. Whereas ‘p-value’ for groups 3 and 4 was < 0.0001 and 0.003 respectively and was statistically highly significant.Conclusion: The present study indicates that pulse oximetry can be used as a routine method for assessing the pulp vitality in primary, young permanent and mature permanent teeth.How to cite this article: Shahi P, Sood PB, Sharma A, Madan M, Shahi N, Gandhi G.

Regenerative endodontic procedures have brought novelty in the arena of dentistry. Stem cell research has paved its way into conserving and utilizing the multipotent stem cells for tissue growth. One such procedure is revascularization which utilizes the apical stem cells for root lengthening and reinforcement in traumatized tooth with an open apex. The present clinical case report has shown that revascularization results in successful root lengthening and apical closure in lesser appointments than conventional specification procedure without weakening the dentinal walls.
